Why in the news?

Minister of Road Transport and Highways Nitin gadkari on Wednesday (18th He said the new system, exclusively for non-compmercial privateles very much as cars, jeeps, and vans, will address the “long-falling concerns” regarding toll plazas. It will go into effect from august 15 and be valid for one year or 200 trips, whichver comes earllier.

KEY TAKEAWAYS:

1. Fastag is an electronic toll collection system managed by the National Payments Corporation of India (NPCI) and the National Highways Authority of India (NHA). Fastag Sticker is usually pasted on the windscreen of a car. It was launched in 2014 as a pilot project and made mandatory at every every toll plaza in the country in 2021.

2. It uses radio frequency identification (RFID) technology to communicate with scanners installed at toll plazas. Once the car crosses a toll plaza, the request toll is automatically deducted from a bank account or a prepaid wallet linked to the fastag.

3. RFID is a wireless tracking system that consists of tags and readers. Radio waves are used to communicate information/identity of objects or people to nearby readers-devices that can be hand-hald or built into fixed posits like poles or builtings. The tags can carry encrypted information, serial numbers and short descriptions. There are also high-memory tags like the ones designed for use in the aviation industry.

4. There are different types of rfid tags: passive tags, semi-passive tags, and active tags. Active rfids use their own power source, mostly batteries. Active tags can ping information every few seconds like beacons, or they can get activated when a reader is in the proximity.

5. Passive rfids, on the other hand, are activated through the reader using the electromagnetic energy it transmits. This is enough power for the tag to transmit information back to the reader. Active Tags have a longer read range, around 300 ft, compared to passive tags. Fastag uses passive rfid tags. Semi-Passive Tags Comprise An Internal Circuit with a Power Source, but rely on the radio waves received from the reader to transmit the response.

6. RFID TAGS Use an integrated circuit and antenna to communicate with a reader using radio waves at several difference frequencies-low frequency (LF), High frequency (HF), and ULTRAGH (UHF). The message sent back by the tag in the form of radio waves is translated into data and analysed by the host computer system.

How is it different from a barcode?

A barcode is a printed series of parallel bars or lines of varying width used for entering data into a computer system. The bars Represents the binary digits zero and one, which represents the digits zero to nine processed by a digital computer. These barcodes are scanned using special optical scanners know as barcode readers. It uses light to read the black-and-head pattern printing on the sticky tag. However, RFID USS RADIO Waves to Communicate Data from Rfid Chips to Readers That Do Not Require a Line of Sight To Obton The Data. An rfid tag can communicate with a powered reader even when the tag is not powered.

Anpr Fastag System (AFS)

➥ The ministry of road transport and highways will soon the barrier-free movement of vehicles throught toll plazas and reduce trave ‘anpr-fastag-based barrier-not tolllling system’ Toll plazas.

➥ This tolling system will combine ‘Automatic Number Plate Recognition’ (Anpr) Technology with the existing ‘Fastag’ system for toll deduction. Under this, vehicles will be charged on their identification using high-perforce anpr camera and fastag readers. The vehicles do not need to stop at toll plaza for this.

Satellite-Based Tolling System

➥ in march, the union minister of transport informed the rajya sabha that the government has deferred the proposed adoption of an ambitious global navigation setllite system (gsS) for tol collection.on. Concerns.

➥ Under the Gnss, The Toll Collection System works with the help of Satellites and on -board unit (obu) fitted in vehicles, and the toll is Calculated Based on the Distance traveled.

➥ Sources said that the gns has been put on Hold as a decision that it will be rolled out on India has its own complete sytem as there are serious privacy concensns regarding India. Vehicle data.

Beyond the Nugget: Navigation with India Contellation (Navic) System

Launch of Satellites by isro.

1. Navic, or Indian Regional Navigation Satellite System (IRNSS), Is an Independent, Stand-Alone Navigation Satellite System Developed by the Indian Space Research Organisation (ISRO). It consists of a seven-seatellite contellation serving bottom defense and civilian needs. According to the website of isro, the three satellites of the concentration are placed in geostationary orbit, and four satellites are placeed in is inclined in geosynchronous orbit

2. The idea for an indigenous gns was conceived in 1999 Following The War in Kargil, During Which India’s Military Could not use the American Global Positioning System (GPS) in the conflict zone. In this regard, the first Satellite, IRSS 1A, was launched on July 1, 2013.

1 [of the satellite] Signifies the completion of the Irnss Contellation “. Howver, Mid-2016 onward, there were reports of failures of the Rubidium Atomic Clocks used in Several Navigation Satellites. Navic Program – Including Replacements for Failed Satellites – Are Fully Operating, The Indian Space Research Organisation (isro).

4. The Navic Satellites Provide Two Types of Services – Standard Positioning Service While is for General and Commercial Use, and Restricted Service WHICH is Meant for The defense for the defense – Over the Indian Landmass. Neighbouring regions.

5. A primary reason to develoop an indigenous satellite navigation system like the irans despite the existence of global systems Such as the GPS (US), Glonassa (Russia), Galleo (Europe), Galina (China), (Japan), is the reliability that it offers in defense use.

Post Read Question
